A cryogenic gas target system was newly developed to produce intense RI beams at the low-energy in-flight radio-isotope beam separator (CRIB) of the University of Tokyo. The main features of the cryogenic gas target system are the direct cooling of the target cell by a liquid N2 finger and the circulation of the target gas that goes through the liquid N2 tank. Hydrogen gas was cooled down to 85-90 K by liquid nitrogen and used as a secondary beam production target which has a thickness of 2.3 mg/cm2 at the gas pressure of 760 Torr. Intense RI beams, such as a 7Be beam of 2×108 particles per second, were successfully produced using the target.
